Description
2型糖尿病を有する人(以下,DM 群)の食行動に対して,食の入り口であり,食を支える基盤である口腔に注目して,新たな視点での食への支援方法を見出すために,食行動の中の咀嚼に関する文献検討を医学中央雑誌(Web. Ver.4),PubMed, Silver Platter CINAHL®を用いて行った.その結果,10件の文献が抽出され,その内容は「咀嚼」「食事摂取所要時間・速度」「早食い」の3項目に分類できた.咀嚼能力が高い人が血糖コントロールは良好で,DM 群は健常群よりも咀嚼能力は低かった.また,食事摂取時の所要時間が短い群ではHbA1c が高く,咀嚼指導により満腹感が上昇した.対象者や比較対照群の性別・年齢・血糖コントロール状況・口腔内の状態や研究方法が結果に影響を与えている可能性が推察された.単一の方法で総合的に咀嚼能力を評価する方法は開発されておらず,咀嚼の機能の要素が検討されていた.「よく噛む」「食べる速さ」は,用語の定義づけがされないまま,個人の主観が評価されていた.咀嚼行動の個別性や複雑性により,定量化や,比較,評価は容易ではないと考えられた.咀嚼や食事摂取時間・速度および咀嚼を支える口腔の機能等が血糖コントロールに与える影響について,科学的な根拠に基づいて知識を提供した研究は行われていなかった.また,咀嚼や食事摂取時間・速度および咀嚼を支える口腔の機能等と血糖コントロールに対する個人の考えも調査されていなかった.
今後,看護援助を行うにあたり,咀嚼や口腔機能の視点からの知識を提供し,行動変容を動機づけることも食行動への支援方法のひとつとなると考えられた.個々の患者のこれまでの生活習慣や価値観・健康観を踏まえた新たな食への支援が必要となってくる.食を取り巻く因子を総合的に検討した包括的な食行動支援方法を開発する必要性が示唆された.

Objectives : The present study aimed to review literature focusing on dietary behaviors(DB)related to mastication among adults with type 2 diabetes mellitus (T2DM). The oral cavity is the entrance to the digestive tract and fundamental to DB. Therefore, we hope to identify novel effective interventions that support the DB of adults with T2DM from the perspective of the oral cavity.
Methods : A search of literature published between 1983 and 2006 was performed using Ichushi-Web (Ver.4), PubMed, and Silver Platter CINAHL®.
Results :
1.Ten primary studies were selected.
2.Findings were classified into the following three categories:“mastication”,“the required time for eating and bite speed”, and“eating quickly”.
3.Individuals with high mastication ability had good glycemic control, and adults with T2DM had worse glycemic control than controls. When nurses focused individuals’ concentration on mastication, the individuals’ satisfaction with eating increased.
4.As no study provided definitions of“biting well”nor“biting speed”, participants’ subjective responses were evaluated.
5.No study investigated individuals’ thoughts regarding mastication, the required time for eating, or oral cavity function.
Discussion :
As one method for evaluating an individual’s mastication has yet to be discovered, research must focus on the elements of mastication ability. Because mastication differs for each individual and is a complex process, it is difficult to compare mastication behavior(MB)between individuals.
Nurses require an understanding of the thoughts of adults with T2DM regarding DB, MB, and the oral cavity. Moreover, nurses must offer information regarding the influence of the oral cavity on glycemic control according to patients’ needs. With this knowledge, adults with T2DM can begin to change their lifestyles. Therefore, this approach is considered effective for supporting DB. Further research is required in order to develop additional effective interventions that comprehensively support DB in consideration of dietary factors.
